The number of STCs received by Solar power system owners is determined by the size of their system and the amount of electricity it is expected to generate over a 15-year period. This is called the deeming period.
The value of STCs is not fixed and can vary depending on market demand. As the number of STCs required to be purchased by retailers each year decreases over time, the value of each STC may also decrease.
The purpose of the SRES is to provide financial incentives for the installation of small-scale renewable energy systems, including Solar power systems. This helps to reduce greenhouse gas emissions and promote the use of renewable energy sources in Australia.
In addition to the SRES, some state and territory governments in Australia also offer their own Solar Rebate programs. These programs may provide additional financial incentives or assistance for installing Solar power systems.
It is important for Solar power system owners to understand the eligibility criteria and requirements of the SRES or any other Rebate program they may be eligible for, as well as the rules and regulations governing the sale or trading of STCs.
